How often does this occur? I actually had the same error once, and this is an error on the side of Overkiz server. The integration recovers from this without issues, thus I would be in favor of closing this PR if this is only a one time error in the log. :-)

Was checking my logs because of updating to the latest HA version. Happened first time and once today, for now.

I am seeing the exact same error for 2 hours now. The CozyTouch app says:

Maintenance

Server currently under maintenance, please try again later

[iMicknl]

@RichieB2B do you see Invalid header value as well? Can you share your full log?

@Wiggum127 which hub do you have?

[RichieB2B]

I have the CozyTouch Bridge v1 with the RJ45 ethernet port. My error message is exactly the same, but it comes from a custom script (not HA):

ClientResponseError during login: 400, message="Invalid header value char:\n\n  b'Cache-Control: no-cache'\n                           ^", url=URL('https://ha110-1.overkiz.com/enduser-mobile-web/enduserAPI/login')

I believe the root cause is that Atlantic disables their API backend but leaves their frontend (webservers) running. They produce strange errors during maintenance. See https://github.com/iMicknl/python-overkiz-api/issues/979#issuecomment-1840694356 for a way to test if the Atlantic API is in maintenance mode.

I'm using the Somfy Connexoon hub. FYI, haven't seen the issue reocurring since last report on 28/11.

[RichieB2B]

@Wiggum127 The next time you see these errors, please check what the Somfy TaHoma app says. If it tells you there is ongoing maintenance, maybe we can figure out which URL they use to check this.

[Wiggum127]

@RichieB2B Should be very lucky to stumble upon the error on time. I only check the HA logs once every so often to see if anything is broken. So changes are very slim I'll be able to provide what you're looking for. Is there anything I can do now already to provide you with more details ?

[iMicknl]

@Wiggum127 do you still face this issue?

[Wiggum127]

@iMicknl Things have been very stable lately. So can't state the I'm still suffering from the issue.

[iMicknl]

Thanks! Let's close the issue for now, but happy to reopen if you face issues again.
